Vulcasteel Roof


The Vulcasteel Roof is an insulated roof panel used for pitched metal roofs. Due to its metal inner and outer sheet, the panel can combine thermal resistance and large spans. The minimum pitch for application is 8°. The panel is often used in public and industrial buildings. The mineral wool insulation core renders the roof inflammable, highly resistant to fire and having excellent acoustics. An additional option is to have a flat inner sheet.

Quality standards:

  • Manufactured complying with ISO 9001 standards.
  • Carries the EPAQ label (European Quality Assurance Association for Panels and Profiles).
  • CE Marked.
